Abstract

La conversion A/N pipeline d'un signal analogique d'entrée se fait à l'aide d'un nouvel algorithme selon la présente invention, produisant un signal numérique de sortie à codage Gray. Le convertisseur A/N pipeline comporte plusieurs étages en cascade à travers lesquels se propage le signal d'entrée analogique. Chacun des étages produit l'un des bits de sortie du signal numérique de sortie et traite en outre le signal pipelinisé. En fonction de l'algorithme de codage Gray, le bit de sortie produit dans un étage détermine si le signal pipeline de cet étage est oui ou non inversé. Dans un convertisseur A/N pipeline utilisant l'algorithme de codage Gray selon l'invention, l'accumulation des erreurs de décalage est généralement très faible. De plus, le fait que l'inversion de signal soit commandée numériquement autorise des réalisations de grande précision qui améliorent encore les performances du convertisseur A/N pipeline selon l'invention. Dans une variante, l'algorithme de codage Gray est modifié pour former un deuxième algorithme qui rend possibles des réalisations à faible nombre de dispositifs.
